I hope you appreciate my work, let’s discuss about today’s project.
What is RC522?
The RC522 is a popular radio-frequency identification (RFID) module used for contactless communication. It operates on the 13.56 MHz frequency and can read and write RFID tags. The module communicates with a microcontroller through a serial interface like SPI (Serial Peripheral Interface) and is often used in conjunction with Arduino and other development boards for RFID-based projects.
RC522 RFID Module with Arduino:
RC522 Pinout:
The RC522 module typically has a Pinout configuration as follows:
- SDA (Serial Data Line):
Used for serial communication with the microcontroller (e.g., Arduino).
- SCK (Serial Clock Line):
Clock signal for synchronization during data transmission.
- MOSI (Master Out Slave In):
Data output from the microcontroller to the RC522 module.
- MISO (Master In Slave Out):
Data input from the RC522 module to the microcontroller.
- IRQ (Interrupt Request):
Optional pin used to signal the microcontroller about events or data availability.
- GND (Ground):
Connection for the ground terminal.
- RST (Reset):
Reset pin for the RC522 module.
- 3V or 5V (Voltage Input):
Power supply pin, typically requiring either 3.3 volts or 5 volts, depending on the module version.
